I don't think that anyone can sensibly argue with all dps jobs (melee/casters/ranged) having rdps parity. BLM is not too far off where it needs to be at the moment, but it could very easily be adjusted. I think that if your argument is that it should do more damage than everyone else because it's personally difficult for you to play well, then you're playing a very risky game given how the dev team interprets such demands and follows up on them with complete reworks.

I will note that PLD has been previously reworked once between Heavensward and Stormblood, and benefited tremendously from it, but I think that's largely because the job ended up with a net surplus of actions compared to other tanks. The problem with a lot of recent job reworks is that they have tended to prune action counts in the name of 'accessibility'. That's what makes them undesirable.
